Photoshop: Video Group: Timeline Go to First Frame of Next Clip

I am a prefessional 2d Storyboarder and I think the new Video Groups is great.
To navigate we have Go to Next Frame, Go to Privious Frame , Go to first Fram and Got to Last frame.

Video Group :Timeline Go to First Frame of Next Clip and select this clip and
Video Group :Timeline Go to First Frame of Previous Clip and select this clip.

I just got this idea that it would be very handy if changing the time in the timeline. If a the new time was over another clip than the currently selected this would automatically be selected so I didnt get the message
"Could Not use the brush tool because the current time is outside the range for the target layer." I think I will post this as a another Idea

the difference is . I am not talking about making a new clip. I am talking about navigating between existing clips in a video group . I am a storyboarder I make a psd file for each shot of the film I wotk on .I import the psd files in premiere where I edur an animatic. In each psd file I make a layer where I would draw the bg and Then I would make at least one video group where i would make severel layers where i draw the characters move around. So for instance I will have 3 layers thecfirst is x frames long the next y frames long the last z frames long. I would like functions where i can flip between the layers in my video group and select this layer so I can work on it. So it would be 2 functions "go to first frame of previous clip and select this clip as active layer" And "go to first frame of next clip and select this clip as active layer" so the idea is related but different.

My idea is question 5. And the one by ammoniteboy is number 4. When I get back to work monday i will post a screen shot of my work setup to explain. -Mads

i have to say that in my cintiq it is not confortable to flip my drawings with the tablet buttons, one of the reasons is that they are "sticky"...so i continue to use arrows on keyboard.
however, with script actions, we can manage to flip frame by frame with automatic selection, but only on F keys , wich is better than nothing....

Even if it was possible to flip between exposures it would be impossible to use any key for the shortcut... photoshop 's "personal" shortcuts sucks....

So it is anough to work on a storyboard but if i have to work on serious "traditional" animation, i 'll use tvpaint....
